The present invention relates to a herbicidal composition having an excellent herbicidal effect, which contains dichloro-3-methylphenoxy)propionanilide as an active ingredient.
(従来の技術)
稲作用の除草剤について既に多数のものが開発されてい
るが、その性能、安全性の向上及び薬害の軽減に対する
市場の要望は、依然として強いものがある。(Prior Art) A large number of herbicides for rice cultivation have already been developed, but there is still strong demand in the market for improved performance, safety, and reduced chemical damage.
また水田雑草の特徴として、その多くは発生時期が一致
せず、長期にわたって発生すると共に、除草剤散布時に
おける雑草の生育状態も、発生前のものからある程度生
育の進んだものまで各柾発育段階のものが混在している
のが常である。このため、除草剤を一回散布しただけで
は満足する結果を得ることができず、数回にわたり除草
剤を施用しなければならない。Furthermore, as a characteristic of rice field weeds, many of them do not occur at the same time and occur over a long period of time, and the growth state of the weeds at the time of herbicide application varies from pre-emergence to somewhat advanced growth. There is usually a mixture of these. For this reason, it is not possible to obtain satisfactory results with just one application of the herbicide, and the herbicide must be applied several times.

れることを見出し、本発明を完成した。(Problem to be solved by the invention) The present inventors have been able to almost completely control weeds ranging from pre-germination to weeds that have grown to a certain extent by simply spraying a low dose of the chemical, and maintain the effect for a long period of time. As a result of intensive research to develop an excellent herbicide that is highly safe for paddy rice, N-(4-methyl-2-pyridyl)-2-(4-
By applying a mixture of (4-cyanophenoxy)phenoxy]propionamide and 2-(2,4-dichloro-3-methylphenoxy)propionanilide in an appropriate ratio, a remarkable synergistic effect that far exceeded expectations was obtained. The present invention was completed based on this discovery.

(作用)
化合物Aを単独で水田用除草剤として土壌処理を行うと
、雑踏発芽前の段階では、水田最強害雑草の一つである
ノビエに対して特に高い除草活性を有している。しかも
水稲に対しては実用上薬害が認められない点がこの薬剤
の大きな特徴である。(Effect) When Compound A is used alone as a herbicide for paddy fields to treat soil, it has particularly high herbicidal activity against field weed, one of the most harmful weeds in paddy fields, at the pre-germination stage. Moreover, a major feature of this drug is that it does not cause any practical harm to paddy rice.
さらに稲直播栽培において、化合物Aを雑草生育初期に
茎葉兼土壌処理を行うと、直播稲に実用上薬害を与える
ことなくノビエを有効に防除できる。Furthermore, in direct-seeding rice cultivation, if Compound A is applied to both the leaves and the soil during the early stage of weed growth, it is possible to effectively control grasshoppers without causing any practical chemical damage to the direct-seeded rice.
すなわち、化合物Aは顕著・な居間選択性を有している
と言え、有用性が大きい。しかしながら、イネ科以外の
雑草に対しては除草効果が充分でなく、またある程度生
育の進んだノビエに対して土壌処理を行う場合には、充
分な除草効果を期待するには雑草発芽前の処理に比べて
薬量を多口に必要とする。In other words, it can be said that Compound A has remarkable selectivity to the living room, and is highly useful. However, the herbicidal effect is not sufficient against weeds other than the grass family, and when performing soil treatment on wild grasses that have grown to a certain extent, the best way to expect a sufficient herbicidal effect is to treat the weeds before they germinate. Requires a larger amount of medication than
一方、化合物Bを単独で水田用除草剤として使用した場

ばかりでなく、ホタルイ、ウリカワ等の多年生雑草に対
しても有効である。しかも、移植水稲に対して安全性が
高く、水田用除草剤として有用性が大きい。しかしなが
ら、ノビエに対する除草効果は完全ではなく、特に生育
期のノビエに対しては除草効果は期待できない。On the other hand, when Compound B is used alone as a herbicide for paddy fields, it is effective not only against annual weeds such as Konagi 2 Kikashigusa and Cyperus japonica, but also against perennial weeds such as Firefly and Paddy. Moreover, it is highly safe for transplanted paddy rice, and is highly useful as a herbicide for paddy fields. However, the herbicidal effect on wild grasses is not perfect, and in particular, it cannot be expected to have a herbicidal effect on wild grasses during the growing season.
化合物Aと化合物Bとを配合した本発明の除草剤組成物
がそれぞれの薬剤の短所を相い補うだけでなく、極めて
顕著な相乗効果を示すことは全く予想外のことであった
。It was completely unexpected that the herbicidal composition of the present invention containing compound A and compound B not only compensates for the shortcomings of each drug, but also exhibits an extremely significant synergistic effect.
本発明の除草剤組成物の各有効成分の配合割合は特に制
限はなく、広い配合比において優れた相乗効果が得られ
るが、好ましくは化合物Aの1重量部に対して、化合物
Bは0.01〜10重量部程度が適当である。There is no particular restriction on the blending ratio of each active ingredient in the herbicidal composition of the present invention, and an excellent synergistic effect can be obtained in a wide range of blending ratios, but it is preferable that Compound B be added to 1 part by weight of Compound A to 0. Approximately 0.01 to 10 parts by weight is appropriate.
